The present invention relates to improvements in change-making machines, one object of the invention-being to provide such a j machiney with means whereby a predeter- 'f mined number` of coins of small denomination are positioned for ejectment in exchange for asingle coin of higher denomination, the ejectingv device being normally locked `and releasable for manual operation by the insertion of a coin of larger denomination.

n `AV further object of this invention is to provide a device of this character which is especially adapted for making change or for j Vendin 'c ar tokens, orthe like, the construction being simp1e,durable and inexpensive, and thoroughly efficienti-*and practical inuse.

With the foregoing'and other objects in view, which will appear as the description A i proceeds, the invention resides in the combination and arrangements of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 is a vertical sectional view through one of the coin tubes with the mecha- I nism in normal position, dotted lines illustrating the position assumed by the parts at the final ejectment of the coins.

Figure 2 is a view, partly in front elevation and partly in transverse vertical section, showing the parts in normal locked position. Figure 3 is a sectional view on line 3-3 of Figure 1.

Figure 4 is a section and `top plan view of the main lever locking member and a portion of its coin released lever.

Referring to the drawings, the numeral 6 designates a cabinet which is vhere shown as provided with a removable cover 7 and With a front wall 8, said wall being provided at its upper portion with a transparent window 9 and at its lower portion with a. vertical slot 10, the purpose of which will presentlyV appear.v The bottom 11 of said cabinet is provided with an outlet opening 12 which is normally covered by a closure 13 `Thus, it will be 1929, serial No. 368,674.

longitudinally slidable in guides 15 so as to be slid inwardly to uncover the opening 12 when itis desired to remove the coins therefrom. Such closure 13 isl provided with' an apertured depending lip 14 which is adapted v55 to cooperate with an apertured` projection 16 in the cabinet for the reception of a padlock 17'. By these means thev closure 18 may be locked in closed position as shown in ,m Figure 1. A *'60 Brackets`18 Within the cabinet support a coin tube 19 which is open atits upper end so that coins 20 of small denomination may be' introduced thereinand will fall downwardlyto rest upon coin guides 21 at the bottom of" vthe tube, the' distancey of 'the guides from `the bottom of said tube ,determining the numberpof coins tobe ejected at each operation, and, as here shown, being',r1 five in number. A slidable coin ejector- 22 is 7 employed and consists of -a plate portion having al forward right-angled'end 23pmvided with a rearwardly extending apertured lug2l and a rear upstanding flange' 25 which limits the forward ej ecting movement of the same to the dotted line position, 'as showninVFigure` 1. A 'The ejector 2 2 is horizontally slidable between apair of guides 26 `and 27 supported j from one wall of the cabinet. q A l,modified bell-crank lever 28 vhaspinand-slot connection 29 with the lug 24 of the ejectingmember 22 and is itself pivotally mountedat 30 to the upper end of a standard 30-mounted upon thebottom fof the 8 casing. The opposite endf31` of the bellcrank lever extends through the aforesaid s1ot"10`sothat :the same maybe manipulated from the exterior of the cabinet, a'spring S ybeing employed'tol normally hold the bell- 0 cranklever in the full line position7 as shown in Figure 1, with the ejector 22 in retracted orrearward position and the operating end j 31 of saidlever elevated.

A vguide 32, arranged to receive the ejected p coins, has an open tray 38 projecting beyond ythe face of the cabinet adjacentv the free end of the ,leverI arm 31v so as to be readily accessible. i

seen that by Vdepressing E arm 31 of the bell-crank lever 28 so as to cause the same to be moved from the full to the dotted line position, the ejector 22 will eject from guides 2l all of the coins 5 below the lower end of tube 19, the portion 23 engaging the edge of the coins during the movement of vthe same from left to right, as viewed in Figure 1, while the portion 22 will rest below the lowermost coin adjacent the lower edge of the tube 19, and thus retain the volume of coins withinthe tube duringthis action and until the ejectordhasiassumed the rearward position, at whichl time the coins which were above those ejected will fall by gravity, the lowermost one resting upon the guides 21 with thepropernumber of coins positioned-forthe next operation. 4

A novel coin-controlled means requires the insertion of a coin 36 (to be changed for a V plurality of vcoins 20) to elejcttherelease and permit manualoperation of thelever 28 for a'coin-changino' operation. To this end, `a coin'chute 34, having an inlet 35, is disposed at one side of the cabinet.l y coin 36when deposited in said chute, falls by gravity and Y against the tension of spring 42 Awhich .acts

to re'storevthe 'catch to locking position. 'Such depression 4of the `lever 28 alsodepresses a lever 43 pivoted at or adjacent'itsrearend to f the rea'r wall f of the cabinet. and having a pin-and-slot connection tat its forwardend 5 with ythe lever 28. The lever 43 beingin contact fwith --the lever 37, further i depresses the flatter suiliciently to release thefcoin-36, which falls to the bottom-'of the cabinet Also when the lever 28vis returnedtby said Ispring S tonormal position, Yitresets levers 43 and 37 for succeeding operations.
